What do I do to a graph if I have these transformations;

Y=f(x+3) and

Y=f(-x)

If anyone could help, it would be much appreciated :)

y=f(x+3) minus the x coordinate by 3.

E.g. f(x+3) for (2,0) would be (-1,0)

This sort of transformation doesn't affect the Y coordinate.

Y=f(-x)

All the x coordinates are reflected in the y axis.

this means that all x coordinates are effectively multiplied by -1.

e.g. (-2,0) would change to (2,0) and (2,0) would change to (-2,0)

Great way for rembering these is alcohol. if alochol is in your system still your hungover and lying dieing in bed, so you always travel horizontaly. if its not your awake and upright vertical.
